We look at the division of 85320181 by 863 
The aim is to understand the frequency of 863 in 85320181.

Let's proceed to step 1:
8 divided by 863 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 863

Step 2:
85 divided by 863 is 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Include the next digit (3) from the dividend after 85, then repeat: 853 / 863

Moving on to step 3:
If we divide 853 by 863, we get 0 and a remainder of 853.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 853 and we're left with 853.
Fetch the next digit (2) from the dividend, attach it to 853 and continue: 8532 / 863

Advancing to step 4:
If we divide 8532 by 863, we get 9 and a remainder of 765.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 7767 from 8532 to get 765.
Include the next digit (0) from the dividend after 765, then repeat: 7650 / 863

Step 5:
863 goes into 7650 8 times with a remainder of 746.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
The remainder is 746 after subtracting 6904 from 7650.
Take the next digit (1) from the dividend and append it to 746, then repeat: 7461 / 863

On to step 6:
7461 divided by 863 is 8 with a remainder of 557.
Record the quotient 8 as the next digit in the result. 
Result so far: 988.0
Subtract 6904 from 7461 to get 557.
Append the next digit (8) from the dividend to 557 and continue with: 5578 / 863

Let's proceed to step 7:
If we divide 5578 by 863, we get 6 and a remainder of 400.
Write down 6 as next digit of the result. 
Result so far: 9886.0
If we take 5178 away from 5578, we end up with 400.
Fetch the next digit (1) from the dividend, attach it to 400 and continue: 4001 / 863

Going ahead to step 8:
When dividing 4001 by 863, we get 4 with a remainder of 549.
Write down 4 as next digit of the result. 
Result so far: 98864.0
The remainder is 549 after subtracting 3452 from 4001.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Moving on to step 9:
5490 divided by 863 is 6 with a remainder of 312.
Record the quotient 6 as the next digit in the result. 
Result so far: 98864.6
Deduct 5178 from 5490 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 10:
When dividing 3120 by 863, we get 3 with a remainder of 531.
Write down 3 as next digit of the result. 
Result so far: 98864.63
Subtract 2589 from 3120 to get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Going ahead to step 11:
The number 863 fits into 5310 6 times, leaving a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 98864.636
Subtracting 5178 from 5310 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 12:
1320 divided by 863 is 1 with a remainder of 457.
Use 1 as the next digit of our solution. 
Result so far: 98864.6361
Subtract 863 from 1320 to get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Advancing to step 13:
The number 863 fits into 4570 5 times, leaving a remainder of 255.
The next digit of our result is 5. 
Result so far: 98864.63615
Subtract 4315 from 4570 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 14:
863 goes into 2550 2 times with a remainder of 824.
Put 2 as the next digit of the answer. 
Result so far: 98864.636152
If we subtract 1726 from 2550, we get 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

On to step 15:
When dividing 8240 by 863, we get 9 with a remainder of 473.
The number 9 becomes the next digit in our result. 
Result so far: 98864.6361529
Subtracting 7767 from 8240 leaves us with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Moving on to step 16:
4730 divided by 863 is 5 with a remainder of 415.
Put 5 as the next digit of the answer. 
Result so far: 98864.63615295
If we subtract 4315 from 4730, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

The quotient of the division is 98864.63615295, and the remainder is 4.15e-07.
